SPECIFICATION forming part of Letters Patent No. 446,394, dated February10, 1891.

Application filed August 26, 1889! Serial No. 321,974. (No model.)

To aZZ whom it may concern:

Be it known that I, SAMUEL J. Snrnnrnn, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Type.- \Vriting Machines, ofwhich the following is a specification.

My invention relates to improvements in type-writers of that classwherein a rotatable type-sleeve is employed, and more particularly toimprovements upon the type-writer shown and described in mypatent, N0.ilLOGG, granted September 17, 1889.

In my present improvement, as in my pre vious invention shown anddescribed in said patent, the type-sleeve reciprocates parallel to theline of printing in either direction from its normal position for thepurpose of bringing each and all the separate type or charactors on thetype-sleeve into position longi tudinally in front of theimpression-hammer; and the rotary movement of the type-sleeve serves tobring each of the separate type or characters on the type-sleeve intoposition radially in front of the impression-hammer, the radial andlongitudinal movements of the type-sleeve taking place simultaneously.

In my present improvement, as in my previous machine, there are thirtykeys and key- 3 levers arranged in three separate rows, the key-leversof each row having a common pivot, the key-levers of onerow operatingsimply to slide the type-sleeve without rotating it, and the key-leversof the other two rows operating to both slide and rotate-thetype-sleeve, and

a series of vertically-slidingstop-pinsare employed for the purpose oflimiting the movement of the type-sleeve.

My present improvement consists in the 4 novel devices and novelcombinations of parts and devices herein shown and described, and moreparticularly pointed out in the claims.

In the accompanying drawings, which form a part of this specification,and in which similar letters of reference indicate like parts,

Figure 1 is a plan view of a type-writer embodying my invention. Fig. 2is an end view. Fig. 3 is a central vertical longitudinal section online 3 3 of Fig. 1. Fig. 4 is a rear 5 view. Fig. 5 is a plan view ofthe keys and key-levers. Fig. 0 is a detail plan view of one set ofreducing-levers by which the mo tion of the key-levers is communicatedto the stop-pins. Figs. Tand S are detail views of the escapementmechanism by which the spacing movement of the paper carriage or rolleris controlled. Fig. 9 is a detail view of the segment-gear by which thetype-sleeve shaft is rotated to bring the faces of the typesleeve whichprint the capitals or figuresinto 6o operation. Fig. 10 is a detailperspective view of the mechanism by which the motion of the key-leversis communicated to the type-sleeve. Fig. 11 is a detail perspective viewof parts hereinafter to be described.

In the drawings, A represents the frame of the machine. The frame A isfurnished with an interior frame or portion A, attached to the outerframe A by screws 60, and upon which frame A the key-levcrs are pivoted.The keys 1 are arranged in three rows of ten keys in a row. Thekey-levers B B 13 0f the three rows of keys are pivoted to shafts b Z)W, mounted on the vertical brackets A extending from the frame A.

O is the type-sleeve, and D D are the stoppins by which the radial andlongitudinal movement of the typesleeve is regulated.

The frame A is provided with front and rear combs or slotted plates AAt. which serve as vertical guides for each of the keylevers B 1-3 B Thenecessary rotary movement is com municated to the shaft 0 of thetype-sleeve O by means of bars F F, which extend across all thekey-levers 1%13 3 Asthekey-levers Bof the first row or rank of keys arerequired to communicate only a sliding movement to the type-s1eeve andare not required to give it any rotary movement, the key-levers B arefurnished with notches b registering with the bars F F, so that when thekey-levers B are actuated neither of the bars F F will be moved. Therotary movement of the typesleeve is communicated from the second row 5of keys from their key-levers B by means of the bar F, and thekey-levers B are furnished with notches I)", which register with the barF, so that the type-sleeve rotating bar F will not be actuated by thekey-levers B and the I00 key-levers B of the final row of keys actuatethe type-slcevc-rotating bar F, these key-levers being provided withnotches bflwhich register with the bar F, so that the bar F will not bemoved when the key-levers 1% are actuated. By thus simply providing thekey-levers B B B with notches or recesses properly registering with thebars F F, I am enabled to communicate the proper rotary movement to theshaft of the type-sleeve for each separate row or rank of keys.

The keys B are arranged in sets of three transversely to the rows, sothat the same eonnectin g mechanism may be employed for communicatingthe necessary longitudinal movement for each set of three keys. One keyof each set is found in each of the three rows or ranks of keys, thekey-levers of each set bein g contiguous to each other. The necessarysliding or longitudinal movement is communicated to the type-sleeve Gfrom each set of the three contiguous key-levers B B B by means of arock-shaft G, having an arm g, furnished with a foot g, which spans thethree keys of the set. There are ten of these rockshafts G, as there areten sets of key-levers B" B B. The rock-shaf ts G are journaled in thevertical brackets A The type-sleeve shaft O is furnished with a slidingrotatable spiral gear G which engages a guide 0 mounted on the frame ofthe machine, and also a slotted guide C, secured rigidly to the shaft C,so that by slidin g the spiral gear 0 through the f rame-guide C theshaft 0 will be rotated and the necessary rotary movement will thus becom municated to the type-sleeve G, as the type-sleeve C is splined tothe shaft 0. The necessary sliding movement is communicated to thespiral gear 0 from the key-lever-actuated bar F by means of a rock-shaftH,having an arm 7L, connected to abracketfon the bar F, which rock-shaftII is furnished with an arm h, which engages an arm 7; of a lever K, theupper end of which is furnished with a pin which engages an annulargroove 0 in the spiral gear 0 In like manner the other bar Fcommunicates the sliding movement in the opposite direction to thetypesleeve through a rock-shaft ll, having arms 7L2, engaging ears f onthe bar F. The rock-shaft H is furnished with an arm 7L3, which engagesan arm k on the lever K, projecting oppositely from the arm k, so thatthe barF will communicate an opposite movement to the lever K andtype-sleeve C from that communicated by the bar F.

The necessary longitudinal movement is communicated to the type-sleeve Cfrom the key-lever-actuated rock-shaft G by means of arms 9 on therock-shaft, which engage levers J, pivoted at j to the frame of themachine, and furnished at their ends with rollers or projections j,which engage cams a H, on the vertical lever N. The lever N is pivotedat N to the frame of the machine, and at its upper end it is furnishedwith a pin a which engages an annular groove 0 in the type-sleeve C.There are two levers J, one

located on each side of the machine, and the lever N is furnished withtwo cams n n, so that the key-levers on one side of the machine willoperate to move the type-sleeve in the opposite direction from those onthe other side of the machine. Thelever N is likewise provided with twoprojecting arms or, which are engaged by a bar or red m on thespringactuated frame or lever M, so that the forks or arms a a willoperate to return the lever N and the type-sleeve C to their normal orcentral position after each impulse or movement of the type-sleeve. Thearms g of the rockshaft G are so rotated in respect to each other to thelever J and to the shape of the cams a a that each set of threekey-levers will give the proper longitudinal movement to the typesleeveto bring the type actuated by such keylevers into proper position forprinting. The type-sleeve O is furnished with a pin or projection c,which engages the spline or longitudinal groove 0 in the shaft 0. Theshaft 0 has a pivot-bearing c c at each end for the purpose of reducingfriction. The pivot c is fixed in place by a set-screw 0 so that theshaft C may be readily removed when desired. The type-sleeve C isfurnished with a series of registering notches c at each end, of asemicircular form at their ends or bases, corresponding accurately tothe size of the stop-pins D, with which they are to engage. The outerportion of these registering notches c is made curved or cam shape, asis clearly indicated at a, so that as the end of the typesleeve engagesthe stop-pin D the stop-pin will serve to not only limit thelongitudinal movement of the type-sleeve, but also the radial movementof the type-sleeve, and thus lock and register it firmly and accuratelyin position, both radially and longitudinally. By thus causing thestop-pin to at once and positively register the typesleevelongitudinally and radially the printing will be done in accurate lineand with proper spacing.

- The stop-pins D are ten in number, there being one stop-pin for eachset of three keylevers 3 B B. Motion is communicated to the stop-pinsfrom the key-levers through the same rock-shaft G and its arms g g bywhich the longitudinal movement is communicated to the type-sleeve. Eachstop-pin is pivoted or otherwise connected to one of the arms 9 Drepresentsthe holes or guides in the frame, through which the stop-pinsreciprocate.

The return ing treadle or lever M is furnished with arms or branches M,which engage the stop-pin-operatin g levers, and thus insures thereturning of the stop-pins to place. The side levers J J are alsoreturned to place by this same returning-treadle M, the arms M havingprojections which fit over the levers J. The main returning-treadle M isalso provided with branches or forks M which bear against the arms 7tand 7a of the typc-sleeve-rotating lever K, so as to return or bring thetype-sleeve G to its normal position radially. The returning-treadle Mis operated by a spring M .By thus con'ibining the type-sleeve-rotatingmechanism, the type-sleeve-sliding mechanism, and thetype-sleeve-registering mechan ism or stop-pins with one and the samereturning-lever M, I am not only enabled to materially simplify themachine, but I also cure a more positive, accurate, and rapid movement.

The guide C before mentioned, which on crates to turn the spiral gear (1as it reciprocates, I make in the form of a segment-gear, as is clearlyshown in Fig. 9,so that by turning or rocking this segment I may changethe case of characters which will be printed. The type-sleeve has ninefaces. Three of these faces-ten characters in each face, or thirtycharacters in all-constitute the lowercase type. Three other of thesefaces constitute the capital letters, and the remaining three faces arefor figures and other characters. 13 y simply turning the segment-gear Cso that the spiral gear 0 will make one-third or two-thirds of arevolution, the capital or figure printing type will be brought intorevolution. The segment-gear C is thus turned by means of a capkey 0 andlever O, which is connected to the segment-gear C by means of a link 0and pin 0*, The figure-key P and its key-lever P are connected with thissame link 0 Springs 0 and link 0 serve to return the levers O and P intoplace, respectively. The segmentgear C is furnished with a lip orprojection C and a set-screw C for adjusting its normal position. Aspring C holds the gear C normally in place.

Q and Q are the inking-ribbon spools. They are journaled on a pivotalframe Q havinga ribbon-guide Q", which partially encircles thetype-sleeve C, an opening being left at the back or rear side for theimpression-hammer R to strike through. A portion of this guide Q ispreferably made movable, the movable part Q being pivoted to the mainportion of the ribbon-frame Q The purpose of making a portion of theribbon-guide movable is to lift the ribbon away from the type-sleevewhen it is desired to remove the type-sleeve and its shaft from themachine. An inking-ribbon q passes from one of the spools Q through orover the ribbon -guide Q and transversely around the type-sleeve, andthence around the other pulley or spool Q. The ribbon-guide serves notonly to guide the inking-ribbon, but also to hold the inking-ribbon outof contact with the type-sleeve, excepting at the instant when and atthe point where the impressionhammer R strikes it. By making theribbonguide of a curved shape, so that it partially encircles thetype-sleeve, and by employing a narrow type-ribbon and arranging it sothat it extends transversely around the type-sleeve,

the type-ribbon is prevented from hiding the printed line; and byemploying a pivotal or movable frame for carrying the type-ribbon andits spools and guides, I am enabled to move the type-ribbon to one side,so as to leave the last Word or letter which has been printed open toview. To facilitate the removal of the type-spools Q Qfrom the frame Q Iprovide the frame Qj with pivoted arms q, having pins (f for thetype-spools to fit and revolve upon. may be readily swung up into aposition indicated by the dotted line in Fig. 3, when the ribbon-spoolmay be readily removed.

Each of the spools Q Q is furnished with a gear f q. The gears q eachfit loosely on the shaft f and are furnished with pins (1, which engagea sliding clutch g splined to the shaft f, so that either one of thegears g" may be made to revolve with the shaft (f. A sliding rod (1having a fork or arm q", serves to push the clutch q 'into engagement.with one of the other gears g", as desired. li y this mechanism eitherone of the spools may be driven in the direction necessary to wind theribbon thereon, and then when the ribbon is all wound upon one spool bysimply shifting the clutch g the other spool will be driven in thedirection necessary to transfer the ribbon thereto. The shaft 1 isfurnished with gear 1 which meshes with a worm s on the shaft S of theescapement mechanism, by which the movement of the paper-carriage iscontrolled. The impression-hammer R is actuated from the rock-shaft ofthe main returning-treadle M by means of an arm M and connectinglink 0',which extend under the key-levers, and is pivoted to the lower arm ofthe impres sion hammer or lever B. The paper-carriage T reciprocates onsuitable guides or ways T on the frame of the machine, and is actuatedby a main spring in the drum 25', through the connecting-strap Thepaper-carriage T is furnished with a rack T in which meshes a gear T onthe escapement-shaft S. The escapement-shaft S is furnished with asleeve S, carrying the worm s, and a pin-wheel s and a clutch .9 It isalso furnished with a sliding clutch 5", held in place by a spring 8which engages the clutch s. The shaft S is also furnished with a sleeve5 and pinwheel 3", having a slot .9 through which a pin 3" on thepin-wheel before mentioned projects. A spring 5 connects the pin s" tothe pin .9 on the back of the pin-wheel The sliding clutch s is actuatedby a bent lever S which is held in place by a spring S The pin-wheel sis engaged by a pawl S", which is actuated by the key-lever or by thespaci ng-leverS, through the connecting mechanism. This eseapementmechanism is of an old and well-known form, and its operation willreadily be understood by those skilled in the art. The sleeve S is looseon the shaft S, and the sleeve 5" is splined to the shaft S. The sleeve5- is on the sleeve S. 13y thus combining the mechanism which operatesthe. ribbon-spools with the escapement mechanism I am enabled tocontinuously change the portion of the ribbon which is in use.

The paper-carriage T is provided with a paper-storage cylinder V, havingan opening The pivoted arms q ICS or closing lip Y, adapted to receiveand engage the edge of the paper. The paper-carriage is also furnishedwith a Iced-roller V the shaft of which has the gear 1.", that engagesthe spacin g-gear 1:. It is also furnished with a paper-feed lever rprovided with a pivot-ed pawl 1". The pawl v is furnished with an arm0", that engages a stop or projection r on the paper-carriage frame, soas to automatically lift the pawl out of engagement with the ratchet orpaper feed gear when the paper-feed lever is in its retracted position.The paper feed lever is held in its retracted position by a spring o. Alight spring o operates to throw the pawl into engagement with theratchet at the first forward movement. of the paper-feedleverthat is tosay, as soon as the paper-feed lever is moved the spring '0 at oncethrows the pawlinto engagement with the ratchet the moment arm r of thepawl is moved out of engagement with the stop v The distance between thelines to be printed is regulated by an adjustable or movable stop-pin rwhich fits in holes in the paper carriage frame, the series of holesbeing provided for the purpose of making lines closer together orfarther apart, as may be desired. A thumb-piece V is rigidly secured tothe paper-carriage frame adjacent to the paper-feed lever, so that theoperator in taking hold of the paper-feed lever to feed the paper intoposition for printing the next line may at the same time and by the samemovement of the hand push the paper-carriage to the opposite side of themachine or place of beginning.
